NUT-LOCK.

Specification of Letters-Patent.

Patented Aug. 21 1906.

Application filed March 5, 1908. Serial No. 304.295.

To all whom it may concern:

Be it known that 1, JOHN V. BERRY, a citizen of the United States, and a resident of Shamokin, in the county of Northumberland and State of Pennsylvania, have made certain new and useful lmprovementsin N ut- Locks, of which the following is a specification.

My invention is an improvement in nutlocks, and particularly in locks 0 eratin in connection with bolts having rig t and aft threads; and the invention consists in certain novel constructions and combinations of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side view of a bolt and nut and my improved locking device, the latter being bent down alongside the nut to lock the latter. Fig. 2 is a similar View, partly broken away, showing the looking device screwed down against the nut, but with the handle portion or shank projecting. Fig. 3 is a detail perspective view of the locking device. Fig. 4 is a top plan thereof, and Fig. 5 is a cross-sectional View on about line 5 5 of Fig. 4 looking toward the juncture of the wings with the handle portion or shank.

The bolt A has right and left threads, as shown, and the nut B is screwed on said bolt, preferably on the right-hand threads thereof, as shown. The locking device has a ring or loop C, which merges at C in the handle or shank l), the wings C of the loop diverging from the curved body of the loop toward their juncture with the shank D and overlapping at their ends at C the body of the loop and its wings C being in cross-section about as shown in F ig. 5, with their inner edges at C formed to fit the threads of the bolt. It will be noticed that the ends of the wings overla at O at their juncture with the shank D an that the locking device is alike on both sides, so that it may be turned on the bolt from either side. It will also be noticed that the open space C outside the circle deguide into mesh with the threads of a scribed by the body portion of the loop provides for the separation of the wings C in the direction of the axis of the loop to a sufficient extent to-permit the spiral in the body of the loop to adapt it to fit the bolt to which it is applied. It, will also be understood that if the nut be dapted to the right-hand threads of the be t the locking device should be adapted to the left-hand threads, and vice versa. After the nut has been turned home and the locking device secured down against the end of the nut the shank or handle D may be bent down alongside the nut, thus locking the same firmly against any movement.

1. A nut-locking device com and a handle portion or shank eading therefrom, the loop havin converging wings connecting with the hen le portion or shank, and having said wings deflected at their juncture with the handle portion in the direction of axis of the loop, whereby to form a spiral for screwing on the bolt, the locking device being alike on both bein adapted to be bent down alongside the nut or locking the same, substantially as set forth.

2. The combination with a bolt having right and left threads, and a nut fitted to one set of Said threads, of a locking device havrising a loop ing a loop fitted to the other set of threads,

and having said loop rovided with converging wings and a hand e or a shank connected therewith, the wings of the loop extending tangentially outside of the circle of the body of the loop and deflected outside said circle in the direction of axis of the loop to roperly olt and mer ing in the handle, substantially as se fort JOHN V. BERRY. Witnesses:
